TOY WIND-WHEEL.

Specification of Letters Patent. 7

Patented May 31, 1921.

Application filed. April 9, 1920. Serial No. 372,726.

To all whom it may concern:

Be it known that I, HERMAN SoHLIRr, a citizen of the United States, residing at Milwaukee, in the county of Glackamas and State of Oregon, have invented certain new and useful Improvements in Toy WVind- Wheels, of which the following is a sp ifi cation.

This invention relates to improvements in toy windwheels, and has for its princlpal object to provide windwheels which w1ll be .oppositely rotated through the action of the wind upon the blades thereof.

Another and equally important object of the invention is to so construct the windwheels and means for rotatably supporting the same one above the other that a minimum amount of labor will be necessary to manufacture the toy consequently. reducing the price of the toy to a very small sum when it is placed uponthe open market.

For the purpose of illustrating this invention there is shown in the accompanying drawings one form thereof which is at present preferred,-since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized and that the invention is not limited to the precise arrangement and organization of these instrumentalities herein shown and described.

In the drawings:

Figure 1 is a perspective view of the toy as set up for use.

Fig. 2 is a detail perspective view of the support for positioning one windwheel above the other.

Fig. 8 is a plan view of the blank from which the lower windwheel blades are constructed.

Fig. 4 is a plan view of the blank from Which the upper windwheel blades are constructed. I p

Like characters of reference indicate like or similar parts throughout the several views of the drawings; in which:

A designates the handle of the toy which has mounted intermediate its extremity a substantially U-shaped bracket 1, and positioned in alined spaced relationship above the bracket and upon the handle are a plurality of staples 2, within which is received the shaft 3 of the lower windwheel B.

The lower windwheel B is formed with a rectangular block 4 constituting the hub,

within which the upper end of the shaft 3 is received; it bemg understood that the lower end of the shaft rests upon the bracket 1 when the toy is assembled, as in Fig. 1. The blades 5 of the windwheel (see Fig. 3) are stamped from a blank to form an angular projection 6 and side and end extensions 7 and 8 respectively, which are bent toward each other to trap the air. The angular pro ection 6 of the blades are each fixed to one of the sides of the block 4 mmal end bent to engage the adjacent side beneath the projection 6 of the adjacent blade, and due to the configuration of the block the blades will extend at right angles to each other, thus trapping the air to rotate the windwheel.

As illustrated the blades 5 are attached to the lower portion of the block 4:, while the upper portion extends considerably thereabove. A piece of stripmetal bent to be substantially U-shaped in configuration has its arms 9 engaged upon two opposite faces of the upper portion of the block and is se-' cured thereto by striking a plurality of teeth 10 into the material of the block. The upper end 11 of the block is preferably flat and has an opening 12 formed therein and each of the arms has a lip opposite ends, and designated respectively 13 and 14. The upper lip 13 extends across the lntervening space between the arms and is bent around the upper edge of the opening formed by striking out the lip 14:, while and the terstruck therefrom from I tween the arms and engages over the lower edge of the opening formed by striking out the lip 13. The lip 13 is formed with an opening 15 vertically alined with the opening 12 and the shaft 16 of the upper windwheel C extends through the opening and rests upon the lip 14, consequently supporting the windwheels C and B one above the other respectively.

The upper windwheel C is also formed with a block 17 which constitutes the hub thereof. The blades of the upper windwheel are struck from a blank, such as is illustrated in Fig. 4, and which has a body 18 and lateral and end extensions 19. The two side extensions and one end extension when bent toward each other trap the air rotating the upper windwheel, and the other end extension 19 are attached as at 20 to the faces of the block. Attention is called to the fact that in attaching the blades of the upper windwheel the extensions are bent in opposite directions to the extensions formed on the blades of the lower windwheel consequently when the air strikes the two windwheels they will be rotated in opposite directions. 'In assembling the windwheel the shaft 3 of the lower .windwheel is placed within the alined staples 2 with its end upon thebraoket 1, Thereupon the shaft 16 of the upper windwheel is passed through the openings 12 and 15 in the U-shaped member, consequently the two windwheels being supported one above the other are freely rotatable with respect to each other.

Attention is particularly called to the extreme simplicity of the present device and the ease which it may be manufactured at very small cost to the retail purchaser.

From the foregoing taken in connection with the accompanying drawings, it is thought that a clear and comprehensive understanding of the construction, operation and advantages of the invention may be had, but while I have shown and described the device as embodying a specific structure, I desire it to be understood that such changes may be made insaid structure, as do not depart from the spirit and scope of the invention as claimed. 1

What I claim is:

1. A toy comprising a standard, a bracket I on the standard, a rotatable wind wheel on the standard having its end supported on member and the lips formed thereon for supporting the upper wind wheel for rotation upon the lower wind wheel.

3. A toy comprising a'standard, a pair of wind wheels carried by the standard one above the other, a rectangular hub in the lower wind wheel, blades attached to the hub, angular portions formed on the blades for engagement each with two of the faces of the hub, and extensions formed on the blades bent to trap theair to wind wheel.

4. A toy comprising a standard, a pair of windwheels carried by the standard one above the other, a rectangular hubon the upper wind wheel, blades attached to the hub, extensions on the blades secured to the rotate the hub, and extensions on the blades bent to trap the air to rotate the windwheel.

In testimony whereof, I aflix my signature hereto.

HERMAN SCHLIRF.
